Hi Stephane,
If you're using a conventional file system on AIX, you can expect a
reduction in performance by moving to 16K from your already imperfect 8K.
See Steve Adam's notes why the DB block size should = the file system buffer
size (www.ixora.com).
And that's *4K* on AIX.
Cheers
Richard

Hi,
All our DB have an 8k block size (8172/aix).
Even the reporting/dss database where data is accessed mainly by full
scan.
Can we quantify the gain in % of switching from an 8k to 16k block size
from
a performance point of view ?
